Predictive Control of Networked Control Systems over Differentiated Services Lossy Networks

Networked control systems are feedback systems where plant and controller are connected through lossy wired/wireless networks. To mitigate communication delays and packet losses different control solutions have been proposed. In this work the model predictive control (MPC) has been improved by introducing transmission options offering different probabilities of packet drops (high priority service and low priority service). This Differentiated Services architecture introduces Quality-of-Service (QoS) guarantees and can be used to jointly design the control command and the transmission strategy. A novel MPC-QoS controller is proposed and its design is obtained by solving a mixed integer quadratic problem.
